Parsing files .log

Rails
1

Good afternoon, I’m starting in ruby,
I am grieving for a parser to a file.

file_example File.open = “foo.txt”, “r”
file_example.each do | line |
puts line
end

here I can print all lines of the file.

but as I can get only specific lines and use them in a function?

ok. I I separate them with regex. but not know how to use these lines
that
separated within a function.

If I understand correctly perhaps you need something like

useful_lines = []
file_example File.open = “foo.txt”, “r”
file_example.each do | line |
if some_test_to_indicate_whether_this_is_a_useful_line( line )
useful_lines << line
end
end
